Build errors (mhash redefinitions)

[gdlx]

When building the master branch with gcc 4.8.3 on CentOS 7.1 with Varnish 4.0.3, I get the following errors:

I had no problem building with Varnish 4.0.2/CentOS 7.0 a few months ago... Tried to un/re-install mhash + mhash-devel with no effect.

I have the same issue on FreeBSD...

Sorry for the delay. It should be fixed now. If you still ran into any issues please raise a new bug. Thanks!
